How to programmatically remove a particular word or line from word document using c# ASP.NET

With the Microsoft.Office.Interop.Word assembly, we get the contents and formatting from the document.

Tip:
Add the Microsoft.Office.Interop.Word assembly to your project. Go to Project -> Add Reference...

To Read File:

using System;
using Microsoft.Office.Interop.Word;

class Program
{
static void Main()
{
// Open a doc file.
Application application = new Application();
Document document = application.Documents.Open("C:\\word.doc");

// Loop through all words in the document.
int count = document.Words.Count;
for (int i = 1; i <= count; i++)
{
// Write the word.
string text = document.Words[i].Text;
Console.WriteLine("Word {0} = {1}", i, text);
}
// Close word.
application.Quit();
}
}


To Write File:

var document = new DocumentModel();

// Add document content.
document.Sections.Add(
new Section(document,
new Paragraph(document, "Hello world!")));

// Save the document to a file.
document.Save("Document.docx");

// Open the document file with Microsoft Word.
Process.Start("Document.docx");
